Abstract
A relay state determination device includes a voltage value acquisition unit, a contact bounce time acquisition unit, and a state determination unit. The voltage value acquisition unit acquires a voltage value between one pair of contacts mutually opened and closed in a relay. The contact bounce time acquisition unit obtains a contact bounce time indicated by the one pair of contacts based on the temporal change in the voltage value after the ON instruction to the relay. The state determination unit compares the contact bounce time with a time threshold value to determine whether or not the relayhas deteriorated.
